About This

• Advanced 3-Flaps Insulation & Tight Seal: Our upgraded pet door features a three-flap system with an added insulation layer, designed to improve insulation and sealing performance compared with traditional two-flap designs. The enhanced materials help block outside temperatures, keeping cold air out in winter and heat out in summer. Side brush seals combined with a powerful bottom magnet create a snug closure that helps minimize drafts, dust, and wind.
• Heavy-Duty All-Aluminum Construction: This pet door is built with a full aluminum alloy frame, reinforced through a premium welding process to enhance structural strength and stability. Compared with standard plastic or steel pet doors, aluminum offers excellent durability while remaining lightweight. It also resists rust and paint chipping, ensuring long-lasting performance even in outdoor conditions.
• Entry for Big Dogs: Designed with larger breeds in mind, the flap opening measures 18.7 x 9.92 inches, comfortably fitting dogs up to 110 lbs. For doos installations, the required cutout size is 10.6 x 18.9 inches. The adjustable tunnel design fits doos between 1.26 and 2.08 inches thick, making it suitable for many home structures. Please check the sizing guide carefully to ensure the right fit for your pet.
• Security Panel with Dual Aluminum Locks: For added control and home security, the door includes a removable closing panel that blocks the opening when needed. Two aluminum locking mechanisms secure the panel from the inside, preventing it from being opened externally. This design helps maintain your home’s security while allowing you to easily control your pet’s access.
• Simple DIY Installation: The pet door can be installed in both interior and exterior doors, making it suitable for many home layouts. Each package includes mounting screws, a cutting template, and detailed instructions to guide you through the process. Just follow the provided steps or installation video to complete the setup with ease.
• Tiylibe Reliable Support & Replacement: Our mission is to give pets the freedom to move safely and comfortably between indoors and outdoors. If the door flap becomes damaged during regular use, our support team can provide a replacement flap, helping extend the life of your pet door and reduce long-term maintenance costs.
